Hope this question fits here,be gentle if not. Where do you guys get most of the music you download and play in your cars. And how do you play them back. Ipod,usb,burn to a cd or what. And why is there such a big difference in the sound quality from one song to the next.Meaning one might sound louder than the other. Sorry to ramble own trying to get a consistent sound
from my collection.........

FYI i use itunes with a iphone4
